WOOL-COMBING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 735,980, dated August11, 1903. Application filed June 5, 1901. Serial No. 63,230. (No model.)

Io durable and effective substitute for the usual dabbing-brusheswhereby the web of wool is pressed down into the spaces between the pinsof the large and small circles of a woolcombing machine. This object weattain in the manner hereinafter set forth, reference being had to theaccompanying drawings, in which- Figure l is a side elevation ofsuiiicient of an ordinary wool-combing machine to illus- 2o trate theapplication of our invention thereto.

. Fig. 2 is a side elevation, on an enlarged scale, of that portion ofthe machine to which our invention particularly relates. Fig. 3 is aSectional plan view of the same. Fig. 4 is a transverse section on theline a a, Fig. 3; and

Fig. 5 is an end view looking in the direction of the arrow b, Fig. 2.

In Fig. 3 of the drawings, l represents part of the outer or largecircle, and 2 part of the 3o inner or small circle, of an ordinarywoolcombing machine, the small circle being much less in diameter thanthe large circle and approaching the latter closely at one point,'sothat the bers of the web of wool which are 5 caused to engage with thepins of the circles at their point of nearest approach will as the pinsdiverge be drawn between them, and thereby combed or straightened.

Vertically-reciprocating brushes are usuthe wool into the spacesbetween-the pins of the circles; but the rapid wear of these brushes isan objection to their employment, and it has heretofore been proposed tosubstitute for the re- 4 5 ciprocating dabbing-brushes fixed plateshaving tapering front ends for thrusting the wool down into the spacesbetween the pins or travelingbelts having theirlower runs graduallyapproaching the tops of the pins for or combinations of such devices,none of which, however, have proven to be as effective for the purposeas the reciprocating brushes. In carrying out our invention, therefore,we propose to retain this dabbing action without the employment of theusual brushes, substituting for the latter reciprocating metallic platesguided by suitable bars, which extend between the rows of pins on thecircles of the machine. In the drawings these reciprocatingdabbing-plates are represented at 3, as many of these plates being, bypreference, employed as there are spaces between the rows of pins on thecircles, and as many of the plates as may be necessary being guided inslots near the forward ends of bars 4, which are located between therows of pins and extend some distance rearwardly beyond thedabbing-plates, the lower edge of each bar projecting below the tops ofthe pins, so as to hold the iibers oi' the wool in engagement with saidpins during the time that the combing or drawing action is beingeffected. In the present instance the inner circle 2 has four rows ofpins, in connection with which are employed three dabbing-plates, andthe outer circle has six rows of pins, in connection with which areemployed ive dabbing-plates. The central dabbing-plate of the set ofthree which operates in conjunction with the four rows of pins of thecircle 2 is guided by an inner bar 4. The central dabbing-plate of theset of three cooperating with the first four rows oi pins of the circle1 is guided by an intermediate bar 4. The outermost of the pair ofdabbingplates which cooperate with the outer rows of pins of the circlel is guided by an outer bar 4, as vshown in Fig. 4.

Each set of dabbing plates has a head 5, which head has a concave socket6 for the reception of a carrier-block 7, mounted upon a transverse rod9, carried by a yoke 10, the carrier-block 7 constituting a segment of asphere and being engaged at the top by the concaved lower end of aconiningscrew l1, which is adapted to a threaded opening in the head 5Vand is secured in place by a lock-nut 12. A similar method of support isprovided for mounting the front ends of the bars 4 upon the yoke 13 atthe forward end of a bar 14, which is secured to or forms part of an arm15,mounted upon a column 16 ,which is located axially in respect to thecircle 2, the rear end of the bar 14 having another yoke 17, whichsupports a transverse rod 9 with spherical carrier-blocks 7 thereon,these carrier-blocks being engaged by concaved lips 19 at the top andbottom of a longitudinal slot formed in the rear end of each of theintermediate and outer bars 4, contact of these lips with the sphericalcarrierblock being eifected by means of a vertical clamp-screw 2Oengaging with ears 2l,

projecting from the rear end of the bar, re-

spectively above and below the slot therein. Similar means are adoptedfor mounting the rear end of the innermost bar 4 upon the end of a bar22, which projects rearwardly from the arm 15. Each of the bars 4 andthe dabbing-plates guided thereby is thus adjustable toward and from thecenter of the machine by shifting the blocks 7 upon the rods 9, so thateach dabbing-plate may occupy its proper central position between tworows of pins and each of the bars can swing laterally upon itscarrier-block 7, so as to insure the maintenance of the lower portion ofthe bar in its proper position between the rows of pins of the circleand prevent it from bearing against the pins of either row with suchforce as to cause undue wear of the same, the lower end of each barbeing thickened, as shown at 23, so as to almost fill the space betweenthe rows of pins between which it isvprojected. This lateral freedom ofmovement of the bars 4, however, in no way affects their verticalrigidity necessary for keeping the wool pressed down into the spacesbetween the pins. In order to effeet the vertical reciprocation of thedabbingplates 3 the yoke 10 carrying the same is secured to theprojecting lower end of an arm 24, vertically guided in suitablebearings on the post 16 and engaged by a cam or eccentric 25 on a shaft26, which is mounted in bearings on said post 16 and has a pulley 27,driven by means of a belt 29 from another pulley 30 on a shaft 31,mounted in bearings at the top of the post 16 and having rotativemovement imparted to it in any suitable manner.

The front edges of the bars 4 are preferably inclined or beveled, asshown in Figs. 1 and 2, so as to aid in pushing the wool down betweenthe rows of pins of the circles; but this is not essential to the propercarrying out of our invention, as the engagement of the wool with thepins may, if desired, be accomplished solely by the action of thereciprocating dabhing-plates.

Where the front edges of the bars 4 are inclined, the forward edges oftheir inn er wings may be cnt away, so as to present recesses extendingabove the tops of the pins and rearwardly beyond the dabbing-plates, asshown, for instance, by dotted lines a: in Fig. 2, and where threedabbing-plates are employed in a set the lower portion of the centraldabbingplate may also be cut away or recessed at the rear, as shown bydotted lines y in Fig. 2, as

this plate does not have to perform as severe duty as the outer platesof the series.

The combination of the pin-carrying circle of awool-combing machine, a bar extending between the rows of pins of saidcircle and having its lower edge projecting at all times below the topsof said pins,and one or more verticallyreciprocated dabbingplates guidedvertically by said bar, subtantially as speciiied.
